OK, not going to try and do a slightly different PHA. Might work, might not.
Putting ourselves in the seat of a Villain, lets call ourselves 'NitBob'. I won't allude to which player I was!
NLH 1/1
UTG - Villain 1 (plays LAG, also switches to TAG for periods...no big bets made all night - but capable of betting draws) - STRADDLES to £2
UTG+1 - Villain 2(very LAG, loves 2 pairs and betting draws heavily) - CALLS
MP - Villain 3 (Very ABC, can play trappy. If he bets big he has it) - CALLS

The pot he can win so far is £284, if Villain 1 calls then NitBob can win £309.Questions:
a. What ranges do you assign to villains 1, 2 & 3? (more importantly 1 & 3)
b. Do you call or fold?
